IlVlPLElVi ENT FOR DRIVING DRIVE-WELL TUBES.

vSPECIFICATION forming part of Letters Patent No. 252,878, dated January 31, 1882.

l Application tiled October 3, 1881. (No model.)

.To all whom it may concern:

Be itknown that l, MATTI-Itas ITIN, a citi- Zen of the United States, residing at St. Paul, in the county of Ramsey and State ot' Minnesota, have invented certain new and useful linprovements in Implements for Driving Drive- VVell Tubes, dre., of which the following is a specification.

This invention relates to implements used in sinking that class of wells known as driven wells;7 and it consists in a hammer or head adapted to be alternately raised and allowed to fall or be forced down upon the drive-tube, and in providing said hammer with a wooden or other suitable block or cushion to bear the brunt of the blow, and a. guiding-tube to insure the hammer striking in the right position, as hereinafter shown. v

The invention further consists in providing` said hammer, wooden cushion, and the cap of the drive-tube with perforations, whereby water may bev conveyed to the drive-tube point. without removing thehatn mer, and at the same time a vent formed for the escape ofthe air, as hereinafter set forth. I attain these objects by the use of the mechanism illus't-ratedin the accompanying drawings, in which- Figure 1 is asectional elevation of the hainmer, guide-tube, and a portion of the upper end of the drive-tube, with the hammer down in contact with the drive-tube cap. Fig. 2 is a cross-section on the line x a2, and Fig. 3 is a cross-section on the line y y, ot' Fig. l. Fig. 4 is an outside elevation, with a portion broken out, showing the position of the hammer, 85e., when partially raised preparatory to striking the blow. Fig. 5 is a sectional view, reduced, of an ordinary well, showing the manner ot' using my invention when sinking in the bottom thereof.

In forming what is known as driven wells a tube with a pointed and perforated end is driven into the ground until a water-bearing stratum is reached, and this driving is usually done with large wooden or metal mauls or sledges; but it frequently occurs that wells areto be driven in the bottoms of ordinary wells, as shown in Fig. 5, under buildings, Src., and in other inaccessible places, where the ordinary mauls could not be used; and to enable the tube to be forced into the earth in almost every per end ot'the tube U, and with its upper end in contact with the interior of the hammer B, as shown in Fig. l. The lower end of the tube C is provided with set-screws d, which are set up toward but not tightly against the tube C, to serve as guides to keep the tube C in the same relative position to the tube A, and to prevent its being lifted up over the cap b.

In the upper part of tbe hammer B a small tube, E, is screwed,l which may be of any desired length, and to' which the ropes or chain-s F,'or the handles for lifting the hammer, are attached. By this arrangement itwill be seen that it the hammer B and tube C are raised upward and then allowed to fall, or are forced downward, a blow will be struck upon the cap b and drive the tube A a short distance into the ground. o

The tube C not only serves as a guideto cause the hammer B D to strike the cap b in the right position, but by its weight adds materially to the force ot' the blow, `while the setscrews d not only serve to keep thetube A in the center ofthe tube C, but by projecting beneath the cap b prevent the hammer being lifted high enough to removeit-from the tubeA.

The wooden block D prevents the caps or coupto which thelit'ting rope or chain is attached,

or the lit'tin g mechanism Gor other means for raising the hammer may be attached directly to the hammer. v It is frequently necessary in sinking wells in.

clay soil, &o., that water be poured 'rnto the drive tube to run out through the point a and lnoisten the earth and to enable me to do this WithoutreniovingthedrivingmechanislnIform perforations g through the hammer B, cushion l), and cap b, so that water poured into the tube E will lind its wabY into the tube A; or if the tube E is notused the water will be poured directly through the pert'orations in the hammer. The pert'orations f/ also serve as vents for the air to escape from the tubes.

Iclaim man)v advantages for the use ot'a tube, E, instead of a rope or chain when the upper end ofthe tube A is some distance below the operators, as in Fig. 5: first, because itenables me to utilize it as a vehicle to convey the water to the tube A, as before described; second, it adds materially to the Weight of the hammer; and, third, it enables me to utilize it as a stiff-rod to force the hammer don-n upon the tube A and add to the force of the blow.

In Fig. 5 one common method of sinking drive-wells is shown, and by the use of my im.

pleinent no necessity remains for the opera'tor to remainin the well after setting7 the point a.

The hammer B may be ot' any desired forni or size, and a segmental collar may be substituted for the set-screws d, if desired.

2. The combination and arrangement ofthe head B, cushion D, tube C, and set-screws d d, and tube A, substantially as lset forth.

3. The combination and arrangement of the head B, cushion D, andcap b, all provided with the perforations g and the tubes C, A, and E, substantially as set forth.l
